The present invention is related to a communication system in which a transmitter transmits cyclically a plurality of mutually related objects to a terminal. If said objects are used in the terminal there is no mechanism to establish whether said objects are consistent, e.g. that they are originated at the same time. To ensure that the objects are consistent, they are combined in a common transport entity. The receiver is arranged to extract only the complete set of mutually related objects from the common transport entity. Consequently, the consistency is always ensured.
Legal claims defining the scope of protection, as filed with the USPTO.
1. Communication system comprising a transmitter for transmitting cyclically a plurality of mutually related objects via a communication network including assembling means for combining the mutually related objects that relate to an application at a given time into a combined transport entity to allow transmission consistency of the objects, wherein the transport entity includes an indication of size for each of the mutually related objects; and a terminal connected to the network for receiving the objects and including processing means for processing the plurality of mutually related objects for extracting the plurality of mutually related objects from the common transport entity and the indication of size for each of the mutually related objects, using the indication of size to determine the position of each object in the transport entity.
2. The communication system according to claim 1 , in which transmitter is for introducing into the combined transport entity an update indicator to indicate that the combined transport entity is updated, and the processing means is for extracting the updated objects from the common transport entity if an update is indicated.
3. The communication system according to claim 1 , in which the transport entity comprises a header indicating the size of the header and the size of the objects combined into the transport entity, and the update indicator includes a version number.
4. A transmitter for transmitting cyclically a plurality of mutually related objects, comprising assembling means for combining said mutually related objects at a given time into a combined transport entity to allow transmission consistency of the objects, wherein the transport entity includes an indication of size for each of the mutually related objects.
5. A terminal comprising: means for receiving a plurality of cyclically transmitted mutually related objects, and processing means for processing the plurality of mutually related objects that relate to an application at a given time and for combining into a combined transport entity for transmission consistency, wherein the transport entity includes an indication of size for each of the mutually related objects, and for extracting the plurality of mutually related objects from the common transport entity using the indication of size to determine the position of each object in the transport entity.
6. A communication method comprising: transmitting cyclically a plurality of mutually related objects that relate to an application via a communication network to a destination, processing the plurality of mutually related objects at a given time that are received at the destination, combining the mutually related objects into a combined transport entity for transmission consistency, wherein the transport entity includes an indication of size for each of the mutually related objects; extracting the plurality of mutually related objects from the common transport entity using the indication of size to determined the position of each object in the transport entity; and processing the plurality of mutually related objects.
7. A signal produced by a system, the signal comprising a cyclic sequence of a plurality of mutually related objects that relate to an application at a given time, combined into a combined transport entity for transmission consistency, wherein the transport entity includes an indication of size for each of the mutually related objects.
8. The signal according to claim 7 , in which the combined transport entity comprises an update indicator.
9. The signal according to claim 8 , in which the combined transport entity comprises a header indicating the size of the header and the size of the objects combined into the transport entity, and the update indicator comprises a version number.
10. A tangible for use by a transmitter, the tangible medium comprising: code for transmitting cyclically a plurality of mutually related objects that relate to an application at a given time from a system and including code for combining the mutually related objects into a combined transport entity for transmission consistency, wherein the transport entity includes an indication of size for each of the mutually related objects.
11. A tangible medium for use by a receiver, the tangible medium comprising: code for receiving a plurality of cyclically transmitted mutually related objects that relate to an application at a given time; code for processing said plurality of mutually related objects combined into a combined transport entity for transmission consistency, wherein the transport entity includes an indication of size for each of the mutually related objects; code for extracting said plurality of mutually related objects from the common transport entity using the indication of size to determine the position of each object in the transport entity.
12. The communication system according to claim 1 , wherein the given time is the same time for each of the mutually related objects.
